Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Specifi cations over the –40°C to 85°C temperature range are
assured by design, characterization and correlation with statistical process
control.
Note 3: The linearity error is calculated by the difference between the
incremental slope of the output and the average slope from –50dBm

to –20dBm. The dynamic range is defi ned as the range over which the
linearity error is within ±1dB.
Note 4: Sensitivity is defi ned as the minimum input power required for the
linearity error within 3dB of the ideal log-linear transfer curve.
Note 5: Logarithmic Intercept is an extrapolated input power level from the
best-fi tted log-linear straight line, where the output voltage is 0V.
